Using The Advanced RFID Calibration

Tag Profiler

The Tag Profiler maps the tag position with optimized read and write power settings.

Before running the Tag Profiler, it is important that the proper Gap Sensing procedure has been followed. (Refer to “Calibrating The Printer” in the Quick Setup Guide.)

To use the Tag Profiler, first ensure that the tag type that you have selected from the Tag Type menu (see “Tag Type” on page 23 for a list of supported tag types) either matches the tag type you are about to calibrate or is at least of the same Class and data length (i.e. 64 or 96 bits). Next, check that Custom Tag is set to Duplicate. The correct defaults will then be set for Custom Tag Class and Custom Tag Len (length).

Prior to initiating the calibration cycle, the Tag Profiler can be optimized by setting appropriate limits on the following four custom entries:

•Custom Start Pos. Identifies the starting position of the calibration scan. The default will start at the Top Of Form (TOF). To avoid inefficient scanning at points far away from the target tag, set the Custom Start Pos. within one inch of the center of the physical tag. E.g., if the center of the tag is physically three inches from the TOF, set Custom Start Pos. to 2 inches (one inch before the center of the tag).

•Custom Scan Len. The distance the Tag Profiler will scan to determine the optimum tag position. For improved performance, set Custom Scan Len. to 2 inches or less. This will prevent the printer from looking for a tag far beyond its actual location.

•Custom Min. Power. Sets the lower level that will be tested during calibration. To speed up calibration, set Custom Min. Power to two points lower than the Custom Read Pwr. that was set prior to initiating calibration.
